As can be seen from the above structures, the side chains extending from the 2 and 6 positions of the oxepane ring may be either saturated or unsaturated. In addition, the bond between carbons 3 and 4 of the ring may also be saturated or unsaturated. The points of unsaturation on the ring and side chains are indicated by the letters a, b, c, d, e, f and g. However, when there is a double bond at b, there is no double bond at c, d and f. When a is unsaturated, the configuration around the a double bond may be either E or Z. It is understood therefore, unless otherwise stated, that when the starting material in a given example has a 6E configuration, the product will have a 6E configuration and when the starting material has a 6Z configuration, the product will also have a 6Z configuration. The carbon at the 3 position may have either the R or the S configuration.

Also within the scope of the invention are those compounds having an epoxide ring in either side chain as illustrated in Formula II. Although several epoxide rings are illustrated in Formula II, at no time is there more than one epoxide bridge in the side chain at the 2 position of the oxepane ring. Those compounds having an oxygen bridge between carbons 3 and 6 (Formula III) are also part of the present invention.

In U.S. Ser. No. 672,918, a method is described for obtaining discrete compounds from the zoapatle plant. The zoapatle plant is a bush about 2 meters high that grows wild in Mexico. Botanically it is known as Montanoa tomentosa according to Cervantes, Fam. Compositae, Tribe Heliantheae; another variety of the species is Montanoa floribunda. The plant is described in great detail in Las Plantas Medicinales de Mexico, third edition, Ediciones Botas (1944).

The plant has been used for centuries in the form of a "tea" or other crude aqueous preparations primarily as a labor inducer for humans. Its use as a utero-evacuant agent has been documented in the literature, but definitive chemical and pharmacological studies have not been described. By utero-evacuant is meant an agent which causes the uterus of warm blooded animals to contract or expel its contents. Such agents are generally employed to induce menses, expel a hydatiform mole, expel or resorb a fetus, induce abortion or delayed labor and in situations in which the contents of the uterus, such as the fetus or placenta, should be evacuated.

As a result of the purification steps described in Ser. No. 672,918, two discrete compounds are isolated. One of the compounds is 2S,3R-6E-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol and the other is 2S,3R-6E-(2-hydroxyethylidene)-2-methyl-2-(5-oxo-4,7,8-trimethyl-6E-nonenyl)-oxepan-3-ol. These compounds are the starting materials for the novel compounds of this invention and are not part of the present invention.

The following schematic diagram illustrates general methods for preparing the monocyclic and bicyclic compounds of the present invention from the naturally occurring substances. The starting materials are designated by the numbers 1 and 25 while the other numbers refer to specific examples which are fully illustrated below. The letters designate the specific reagent or reagents employed in the reaction. Although a compound having an E configuration at the 6 position may be prepared by a given example, it should be understood that the same process may be employed for compounds having a Z configuration at the 6 position. As can be seen from the diagram, the intermediate compounds formed by the illustrated processes may be used as starting materials for other compounds. However, the end products and the intermediates both possess useful activity. ##STR3##

The compounds of this invention are prepared by using the naturally occurring compounds as the starting material. The compounds that are prepared for a given series are generally employed as the starting materials for all of the other compounds in that series.

Those compounds wherein n is equal to or greater than 1 are prepared by reacting an appropriately substituted compound having an acyl halide grouping in the 6 position with diazomethane in an appropriate solvent. Suitable solvents include diethyl ether, tetrahydrofuran, dioxane and the like. The resulting diazoketone is then rearranged to the homologous acid. The length of the side chain can be further increased by converting the acid thus obtained to the acid halide and reacting the acid halide with diazomethane as described above. In this way the length of the side chain can be increased to the desired length.

Those compounds of Formula II having an epoxide ring on either of the side chains are prepared by reacting the unsaturated compound with a peracid such as, for example, m-chloroperoxybenzoic acid, or by reaction with vanadylacetylacetonate/t-butyl hydroperoxide or hydrogen peroxide/sodium hydroxide.

Those compounds of Formula IV are prepared by reacting the appropriately substituted compound of Formula I having an unsaturated double bond at a with an oxidizing reagent such as, for example, Jones reagent in an appropriate solvent. Suitable solvents include acetone, 2-butanone and the like.

Those compounds of Formula III having an oxygen bridge between carbons 3 and 6 are prepared by reacting those compounds of Formula I wherein R₂ or R₃ is hydroxy or oxo, a is unsaturated, n=0 with an appropriate agent such as p-toluenesulfonic acid, manganese dioxide and platinum oxide/sodium bicarbonate, for example. These reactions are carried out in a suitable solvent, such as benzene, toluene, xylene and the like. The reactions are generally carried out at room temperature although elevated temperatures may be employed in some cases.

The initial extract from which the purified materials are obtained is prepared from the zoapatle plant through a series of extraction and purification steps. These procedures are described in detail in Ser. No. 672,918. The material obtained as a result of this purification procedure is a mixture containing at least three components as evidenced by gas chromatography. The presence of utero-evacuant materials in the mixture is determined through the use of procedures employed for the detection of uterine contractions and interruption of pregnancy in female animals.

The compounds of the present invention have also been found to possess utero-evacuant properties. They are effective in inducing uterine contractions when administered in doses ranging from about 0.25 mg./kg. to about 100 mg./kg. The compounds are effective in interrupting pregnancy at dosage levels between about 2.5 mg./kg. and 400 mg./kg. The actual dosage employed will depend upon the species of animal to which the compound is administered. The compounds can be administered in formulations prepared according to acceptable pharamceutical practices. Suitable formulations include solutions, suspensions and solid dosage forms in pharmaceutically acceptable carriers. They can be administered perorally or intravenously or in any conventional manner in accordance with acceptable pharmaceutical practices.

In addition to their activity as utero-evacuants, many of the compounds of the present invention have been found to possess useful activity as central nervous system depressants. Activity at doses as low as 3.7 mg./kg. has been observed.

The following describes the invention in greater particularity and is intended to be a way of illustrating but not limiting the invention.

EXAMPLE 1 2S,3R-6E-(2-Hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol ##STR4##

The crude extract obtained by extracting the leaves of the zoapatle plant (50 g.) is dissolved in ether (5 l.) and the resulting solution is filtered and washed with saturated sodium bicarbonate solution (500 ml.).

EXAMPLE 3 2S,3R-6-(2-Acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol

A sample of 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol (2.6 g.) is dissolved in benzene (200 ml.) and pyridine (20 ml.). The solution is cooled to 0° under nitrogen and treated with an excess of acetyl chloride (15 ml.) during a 15 min. period. The mixture is allowed to stir for 2 hrs. followed by the addition of ether (300 ml.). The organic layer is washed with saturated cupric sulfate solution (3×200 ml.), dried (MgSO₄) and evaporated in vacuo to give a brown oil.

The oil is chromatographed on a SilicAR column using ether:petroleum ether (2:3) as the eluting solvent. The less polar fraction is eluted to afford 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (1.3 g.) and the more polar fraction is eluted to afford 2S,3R-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol (1.1 g.):

EXAMPLE 60 2S-2-Methyl-6-carbmethoxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one

Method A. An excess of diazomethane is added at 0° to a mixture of 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one (350 mg.) and ether (20 ml.). The resulting mixture is treated with glacial acetic acid (10 ml.) and then washed with 10% aqueous sodium bicarbonate solution. The organic layer is dried and evaporated to give 2S-2-methyl-6-carbmethoxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one.

Method B. A mixture of 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one (350 mg.), methanol (10 ml.) and concentrated sulfuric acid (0.1 ml.) is refluxed for 5 hrs. under nitrogen, then treated with water (50 ml.) at 0°. Most of the methanol is removed in vacuo and the residue is extracted with ether. The organic layer is dried and evaporated to give 2S-2-methyl-6-carbmethoxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one.

The following compounds are prepared by the methods of Example 60 by substituting an equivalent amount of the appropriate starting material for 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one.

Similarly, by substituting an appropriate alcohol for methanol in the procedure of Example 60, (Method B), the corresponding esters are formed. Thus, for example, ethanol, propanol, t-butanol and benzyl alcohol afford the ethyl, propyl, t-butyl and benzyl esters respectively.

EXAMPLE 61 2S,3R-3-Acetoxy-2-methyl-6-carbmethoxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

Following the procedures of Example 60 but substituting an equivalent amount of 2S,3R-3-acetoxy-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane for 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one, 2S,3R-3-acetoxy-2-methyl-6-carbmethoxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane is obtained.

The following compounds are prepared by the methods of Example 61 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

Similarly, by substituting an appropriate alcohol for methanol in the procedure of Example 61, (Method B), the corresponding esters are formed. Thus, for example, ethanol, propanol, t-butanol and benzyl alcohol afford the ethyl, propyl, t-butyl and benzyl esters respectively.

EXAMPLE 64 2S-2-Methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one, sodium salt

A solution of 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one (350 mg.) in 1:1 tetrahydrofuran:water (10 ml.) is titrated with an equivalent amount of 1 N sodium hydroxide solution. The resulting solution is evaporated to afford 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one, sodium salt.

Similarly, by substituting other basic hydroxides for sodium hydroxide in the procedure of Example 64, the corresponding salts are formed. Thus, for example, potassium hydroxide and ammonium hydroxide afford the potassium and ammonium salts respectively.

The following compounds are prepared by the method of Example 64 by substituting an equivalent amount of the appropriate starting material for 2S-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-one.

EXAMPLE 65 2S,3R-3-Acetoxy-2-methyl-6-chloroformylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

A solution of oxalyl chloride (1.65 ml.) in dry benzene (5 ml.) is slowly added to a stirred solution of 2S,3R-3-acetoxy-2-methyl-6-carboxymethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (394 mg.) in dry benzene (15 ml.) at 0°, and the mixture stirred at 0° for 1 hr. The solvent and excess of oxalyl chloride are removed in vacuo to afford 2S,3R-3-acetoxy-2-methyl-6-chloroformylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

EXAMPLE 66 2S,3R-3-Acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

To a well chilled (-30°) and stirred solution of anhydrous ammonia (34 mg.) in dry methylene chloride (25 ml.) is slowly added a solution of freshly prepared 2S,3R-3-acetoxy-2-methyl-6-chloroformylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (413 mg.) in dry methylene chloride (25 ml.) over a period of 3 hrs. while maintaining the reaction temperature below 0°. The solvent is evaporated in vacuo to afford 2S,3R-3-acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

Similarly, by substituting appropriate amines for ammonia in the procedure of Example 66, the corresponding amides are prepared. Thus, for example, dimethylamine, ethylamine, benzylamine and diphenylamine afford the dimethylamide, ethylamide, benzylamide and diphenylamide respectively.

Similarly, by substituting hydrazines and substituted hydrazides for ammonia in the procedure of Example 66, the corresponding acylhydrazides are formed.

EXAMPLE 67 2S,3R-3-Acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-hydroxy-7-nonenyl)-oxepane

To a solution of 2S,3R-3-acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (381 mg.) in ethanol (20 ml.) at 0° is slowly added sodium borohydride (40 mg.) and the mixture stirred at 0° for 5 minutes. The mixture is then quickly treated with saturated aqueous ammonium chloride solution and extracted with chloroform. The chloroform extract is washed with brine, dried and evaporated to dryness in vacuo to afford 2S,3R-3-acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-hydroxy-7-nonenyl)-oxepane.

Similarly, by substituting appropriate keto amides for 2S,3R-3-acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane in the procedure of Example 67, the corresponding hydroxy amides are formed. Thus, for example, the dimethylamide and ethylamide of Example 66 afford the corresponding hydroxyamides.

The following compounds are prepared by the method of Example 67 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-2-methyl-6-carbamoylmethylene-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

EXAMPLE 118 2S,3R-3-Acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-[4,8-dimethyl-5-(p-nitrophenoxy)imino-7-nonenyl]-oxepane

A solution of 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (422 mg) in absolute ethanol (15 ml) is treated with p-nitrophenylhydroxylamine (250 mg) and a trace of hydrochloric acid. After stirring for 72 hrs at 25° C., the ethanol is evaporated and the mixture is purified by chromatography to afford 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-[4,8-dimethyl-5-(p-nitrophenoxy)imino-7-nonenyl]-oxepane.

Similarly, by substituting other aromatic hydroxylamines for p-nitrophenylhydroxylamine in the above procedure, the corresponding oximes are formed. Thus, phenylhydroxylamine and dinitrophenylhydroxylamine afford the phenoxyimino and dinitrophenoxyimino compounds respectively.

EXAMPLE 119 2S,3R-3-Acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-methoxyimino-7-nonenyl)-oxepane

A solution of 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (422 mg) in anhydrous pyridine (2 ml) is treated with methoxylamine hydrochloride (105 mg) under nitrogen. After standing for 24 hours at 25° C., the reaction mixture is poured into water and extracted with chloroform. The chloroform extract is washed with dilute aqueous sodium bicarbonate and saturated salt solution, dried and evaporated to afford 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-methoxyimino-7-nonenyl)-oxepane.

Similarly by substituting other alkoxyamine hydrochlorides for methoxylamine hydrochloride in the procedure of Example 119, the corresponding oximes are formed. Thus, ethoxylamine hydrochloride, butoxylamine hydrochloride and O-phenoxy hydroxylamine hydrochloride afford the ethoxyimino, butoxyimino and phenoxyimino compounds respectively.

The following compounds are prepared by the procedure of Example 119 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

The mixture is refluxed for 3 hrs, cooled, additional benzene is added and the reaction mixture is washed with water. The organic phase is dried over potassium carbonate and evaporated to afford 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-benzoyloxyimino-7-nonenyl)-oxepane.

Similarly, by substituting other acyl chlorides for benzoyl chloride, in the procedure of Example 120, the corresponding acyloximes are formed. Thus acetyl chloride and butyryl chloride afford the acetoxyimino and butyryloxymino compounds respectively.

The following compounds are prepared according to the procedure of Example 120 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-hydroxyimino-7-nonenyl)-oxepane and employing the appropriate acylating agent.

EXAMPLE 123 2S,3R-3-Acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-[4,8-dimethyl-5-(2,4-dinitrophenylhydrazono)-7-nonenyl]-oxepane

A solution of 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (422 mg) in ethanol (10 ml) is treated with a standard acidic solution of 2,4-dinitrophenylhydrazine in aqueous ethanol at 50° C. for 3 hrs. The reaction mixture is cooled to room temperature and water (35 ml) is added. The solvent is decanted and the residue washed with additional water until it is neutral. The residue is then dissolved in methylene chloride, washed with saturated salt solution, dried and evaporated to give 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-[4,8-dimethyl-5-(2,4-dinitrophenylhydrazono)-7-nonenyl]-oxepane.

Similarly, by substituting other aromatic hydrazines for 2,4-dinitrophenylhydrazine in the procedure of Example 123, the corresponding aromatic hydrazones are formed. Thus phenylhydrazine and p-bromophenylhydrazine afford the corresponding phenylhydrazone and p-bromophenylhydrazone compounds respectively.

The following compounds are prepared according to the procedure of Example 123 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

EXAMPLE 124 2S,3R-3-Acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-p-bromobenzenesulfonylhydrazono-7-nonenyl)-oxepane

A solution of 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (422 mg) in absolute ethanol (20 ml) is treated with p-bromobenzenesulfonylhydrazide (427 mg) and a trace of hydrochloric acid. After stirring at room temperature for 18 hr, the solution is evaporated, the residue taken up in methylene chloride, filtered and evaporated to afford 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-p-bromobenzenesulfonylhydrazono-7-nonenyl)-oxepane.

Similarly, by substituting other sulfonylhydrazides for p-bromobenzenesulfonylhydrazide in the procedure of Example 124, the corresponding sulfonylhydrazones are formed. Thus, benzenesulfonylhydrazide and p-toluenesulfonylhydrazide afford the benzenesulfonylhydrazono and toluenesulfonylhydrazono compounds respectively.

The following compounds are prepared according to the method of Example 124 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-acetoxyethylidene-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane and employing the appropriate sulfonylhydrazide.

EXAMPLE 126 2S,3R-3-Acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(5-benzoylamino-4,8-dimethyl-7-nonenyl)-oxepane

To a mixture of 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(5-amino-4,8-dimethyl-7-nonenyl)-oxepane (422 mg.) and N,N-dimethylaniline (0.14 ml.) is added benzoyl chloride (0.155 ml.). The mixture is heated and stirred at 90° for 3 hrs., cooled and poured into dilute hydrochloric acid and extracted with ether. The ethereal extract is dried and evaporated to give 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(5-benzoylamino-4,8-dimethyl-7-nonenyl)-oxepane.

Similarly, by substituting other acyl chlorides for benzoyl chloride in the procedure of Example 126, the corresponding acylamines are obtained. Thus acetyl chloride and butyryl chloride afford the 5-acetoxy and 5-butyryloxy compounds respectively.

EXAMPLE 127 2S,3R-3-Acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-methylamino-7-nonenyl)-oxepane

The solution is stirred at 25° for 72 hrs., then worked-up as described in Example 125 to give 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-methylamino-7-nonenyl)-oxepane.

Similarly, by substituting other primary amines for methylamine in the procedure of Example 127, the corresponding primary amines are formed. Thus ethylamine and phenylamine afford the 5-ethylamino and 5-phenylamino compounds respectively.

The following examples are prepared by the method of Example 127 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-acetoxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane and employing the appropriate primary amine.

EXAMPLE 133 2S,3R-Acetoxy-6-(2-methoxyethylidene)-2-methyl-2-(5-acetoxy-4,8-dimethyl-7-nonenyl)-oxepane

(A) Following the procedure of Example 141, but substituting an equivalent amount of 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(5-acetoxy-4,8-dimethyl-7-nonenyl)oxepane for 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane the 2-bromoethylidene derivative is obtained. A mixture of sodium amide (39 mg) and tetrahydrofuran (10 ml) is treated with dry methanol (32 mg) in tetrahydrofuran (1 ml) at 0° under argon. The 2-bromoethylidene derivative (450 mg) is added and the resulting mixture is refluxed for 2 hrs. The mixture is treated with water (20 ml) and ether (50 ml) and the organic layer dried and evaporated to afford 2S,3R-3-acetoxy-6-(2-methoxyethylidene)-2-methyl-2-(5-acetoxy-4,8-dimethyl-7-nonenyl)-oxepane.

Similarly, by substituting other alcohols for methanol in the above procedure, the corresponding ethers are formed. Thus, phenol, ethanol and cyclohexanol afford the phenyl ether, ethyl ether and cyclohexyl ether respectively.

(B) To a mixture of sodium amide (39 mg) and tetrahydrofuran (20 ml) is added 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(5-acetoxy-4,8-dimethyl-7-nonenyl)-oxepane (400 mg) in tetrahydrofuran (1 ml) at 0° under argon. The mixture is allowed to warm to room temperature and is treated with an excess of methyl iodide (1 ml). The resulting mixture is stirred overnight and then treated with water (30 ml) and ether (50 ml). The organic layer is dried and evaporated to afford 2S,3R-3-acetoxy-6-(2-methoxyethylidene)-2-methyl-2-(5-acetoxy-4,8-dimethyl-7-nonenyl)-oxepane.

Similarly by substituting other halides for methyl iodide in this procedure, the corresponding ethers are formed. Thus, allyl bromide, benzyl bromide and ethyl iodide afford the allyl ether, benzyl ether and ethyl ether respectively.

The following compounds are prepared according to the procedure of Example 133 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(5-acetoxy-4,8-dimethyl-7-nonenyl)-oxepane and employing the appropriated alkyl halide.

A solution of 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol (600 mg) in benzene (5 ml) is treated, while stirring, with dihydropyran (7.8 ml) and p-toluenesulfonic acid monohydrate (3 mg) at room temperature under nitrogen for 1.2 hrs. The benzene solution is washed with 10% aqueous sodium carbonate solution, dried and the solvent removed in vacuo to afford the crude product (871 mg) which is chromatographed on a SilicAR column using ethyl acetate-hexane (1:20) as the eluting solvent. The major fraction is eluted to afford 2S,3R-6-[2-(tetrahydropyran-2-yloxy)-ethylidene]-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-3-(tetrahydropyran-2-yloxy)-oxepane (395 mg).

EXAMPLE 137 2S,3R-3-Acetoxy-6-(2-nitrooxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

Nitric acid (95%, 0.65 ml) is slowly added to acetic anhydride (1.98 ml) at -25° C. followed by the addition of 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (380 mg) at -20° C. The stirred mixture is slowly warmed to 0°-5° C. within 20 minutes. The mixture is then poured over ice, neutralized with sodium bicarbonate and extracted with ether.

EXAMPLE 141 2S,3R-3-Acetoxy-6-(2-bromoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

To a mixture of 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (390 mg.), pyridine (2 ml.) and ether (30 ml.) is added an excess of phosphorous tribromide (540 mg.) at 0° under nitrogen. The resulting mixture is stirred for 2 hours and poured into water (30 ml.). The mixture is then extracted with ether (3×30 ml.), the organic layers are combined, washed with saturated curpic sulfate, dried and evaporated in vacuo to give 2S,3R-3-acetoxy-6-(2-bromoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

Similarly, by substituting phosphorous trichloride for phosphorous tribromide in the procedure of Example 141, the corresponding chloride is obtained.

The following compounds are prepared according to the procedure of Example 141 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane and employing the appropriate phosphorous trihalide.

EXAMPLE 142 2S,3R-3-Acetoxy-6-(2-mercaptoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

A solution of thioacetic acid (78 mg.) in absolute ethanol (20 ml.) is neutralized with potassium hydroxide (56 mg.) and 2S,3R-3-acetoxy-6-(2-bromoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (440 mg.) is added at 0°. The reaction mixture is allowed to warm to room temperature and stirred for 6 hours. The resulting mixture is treated with water (20 ml.) and the ethanol is removed in vacuo. The residue is extracted with ether; the combined organic phase is dried and evaporated to give 2S,3R-3-acetoxy-6-(2-mercaptoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

The following compounds are prepared according to the procedure of Example 142 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-bromoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

EXAMPLE 143 2S,3R-3-Acetoxy-6-(2-methylthioethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane

Methyl mercaptan (1 g.) is added to a mixture of sodium hydride (24 mg.) and tetrahydrofuran (10 ml.) at -20°. After 1 hour of stirring, the mixture is allowed to warm to room temperature and stirred for 1 hour. To the resulting suspension 2S,3R-3-acetoxy-6-(2-bromoethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (450 mg.) in tetrahydrofuran is slowly added and the resulting mixture is stirred for 16 hours. The mixture is treated with water (30 ml.) and ether (60 ml.). The organic layer is dried and evaporated to afford 2S,3R-3-acetoxy-6-(2-methylthioethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

Similarly, by substituting other mercaptans for methyl mercaptan in the procedure of Example 143, the corresponding thioethers are obtained. Thus, cyclopentyl mercaptan, thiophenol and benzylmercaptan afford the cyclopentyl thioether, phenylthioether and benzylthioether respectively.

The following compounds are prepared according to the procedure of Example 143 by substituting an equivalent amount of the appropriate starting material for 2S,3R-3-acetoxy-6-(2-bromoethylidene)-2-methyl-2-(4,8-dimethyl)-5-oxo-7-nonenyl)-oxepane.

A solution of 2S,3R-3-acetoxy-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane (380 mg.) in benzene (5 ml.) is treated with p-nitrophenylisocyanate (180 mg.) in benzene (5 ml.) at room temperature under nitrogen for 15 minutes. Removal of the solvent affords 2S,3R-3-acetoxy-6-(2-p-nitrophenylcarbamoyloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepane.

Similarly, by substituting other isocyanates for p-nitrophenylisocyanate in this procedure, the corresponding urethanes are obtained. Thus, methylisocyanate and phenylisocyanate afford the methyl urethane and phenyl urethane respectively.

The reaction mixture is maintained at 90° for 12 hours, then cooled and poured into ice water and extracted with ether. The ether layer is dried and evaporated to afford 2S,3R-6-[2-(tetrahydropyran-2-yloxy)-ethylidene]-2-methyl-2-(4,8-dimethyl-5-thioxo-7-nonenyl)-3-(tetrahydropyran-2-yloxy)-oxepane.

EXAMPLE 153 2S, 3R-6-(2-Hydroxyethylidene)-2-methyl-2-(5-hydroxy-4,5,8-trimethyl-7-nonenyl)oxepan-3-ol

2S,3R-6-(2-Hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol (407 mg.) is dissolved in tetrahydrofuran (8 ml.). The solution is cooled to -78° under nitrogen and treated slowly with an excess of methyllithium (3 ml., 1.6 M in ether). The reaction mixture is kept at -78° for 10 minutes and then slowly warmed to room temperature by removing the cooling bath. The mixture is then treated with ether (100 ml.) and saturated NH₄ Cl solution (50 ml.). The organic layer is washed with water (50 ml.), dried (MgSO₄) and evaporated in vacuo to give 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(5-hydroxy-4,5,8-trimethyl-7-nonenyl)-oxepan-3-ol (410 mg.).

Similarly, by substituting other organolithium or organomagnesium halides for methyllithium in the procedure of Example 153, the corresponding alcohols are formed. Thus, n-butyllithium, ethyllithium, allyl magnesium bromide and 1-propenyl magnesium bromide afford the n-butyl carbinol, ethyl carbinol, allyl carbinol and 1-propenyl carbinol, respectively.

The following compounds are prepared by the procedure of Example 153 by substituting an equivalent amount of the appropriate starting material for 2S,3R-6E-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol and employing the appropriate organo-metallic reagent.

A solution of 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol (600 mg.) in anhydrous dioxane (10 ml.) is added at room temperature to a stirred mixture of lithium acetylide ethylenediamine complex (2.6 g.) in anhydrous dioxane (30 ml.). A stream of acetylene is passed through this stirred mixture for 24 hours. The reaction mixture is then treated with a saturated ammonium chloride solution (50 ml.) and ether (200 ml.). The organic phase is dried and evaporated in vacuo to give a brown oily residue which is plate chromatographed on silica gel, using ethyl acetate-cyclohexane (1:1) as the developing solvent. The most polar band is eluted with isopropanol-chloroform (1:1) to afford 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-ethynyl-5-hydroxy-7-nonenyl)-oxepan-3-ol (246 mg.).

EXAMPLE 157A 2S,3R-6-(2-Hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-hydroxy-5-propynyl-7-nonenyl)-oxepan-3-ol

Lithium propynide is generated by slow addition of n-butyllithium (4 mmole) to a solution of propyne (1 ml.) in tetrahydrofuran (15 ml.) at -78° under argon. To this reagent is added 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-oxepan-3-ol (330 mg.) in tetrahydrofuran (1 ml.) at room temperature and the resulting mixture is stirred for 5 hours. The mixture is treated with ether (50 ml.) and saturated ammonium chloride solution (30 ml.). The organic phase is dried and evaporated in vacuo to afford 2S,3R-6-(2-hydroxyethylidene)-2-methyl-2-(4,8-dimethyl-5-hydroxy-5-propynyl-7-nonenyl)-oxepan-3-ol.

Similarly by substituting other 1-alkynes for propyne in the procedure of Example 157A, the corresponding alcohols are formed. Thus, lithium pentynide and lithium hexynide afford the 1-pentynyl carbinol and 1-hexynyl carbinol respectively.

To a mixture of (methyl)-triphenylphosphonium iodide (406 mg.) and tetrahydrofuran (10 ml.) is added n-butyllithium at -20° under argon; 2S,3R-6-(2-trimethylsiloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-3-trimethylsiloxyoxepane (504 mg.) is added to this reagent and the mixture is stirred for 30 minutes. The resulting mixture is allowed to warm to room temperature and is stirred for another 30 minutes. The mixture is then poured into buffer (pH=7, 30 ml.). The resulting mixture is then extracted with ether. The combined organic phase is dried and evaporated to afford 2S,3R-6-(2-trimethylsiloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-methylene-7-nonenyl)-3-trimethylsiloxyoxepane.

EXAMPLE 159 2S,3R-6-(2-Trimethylsiloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-ethylidene-7-nonenyl)-3-trimethylsiloxyoxepane

Following the procedure of Example 158 but substituting an equivalent amount of (ethyl)-triphenylphosphonium iodide for (methyl)-triphenylphosphonium iodide, 2S,3R-6-(2-trimethylsiloxyethylidene-2-methyl-2-(4,8-dimethyl-5-ethylidene-7-nonenyl)-3-trimethylsiloxyoxepane is obtained.

Similarly by substituting other phosphonium halides for (ethyl)-triphenylphosphonium iodide in the procedure of Example 159, the corresponding alkylidene derivatives are formed. Thus, (benzyl)-triphenylphosphonium chloride and (butyl)-triphenylphosphonium bromide afford the benzylidene and butylidene derivatives respectively.

The following compounds are prepared according to the procedure of Example 159 by substituting an equivalent amount of the appropriate starting material for 2S,3R-6-(2-trimethylsiloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-3-trimethylsiloxyoxepane and employing the appropriate phosphonium halide.

Lithium diisopropylamide is generated from diisopropylamine and n-butyllithium at -20° under argon in tetrahydrofuran (10 ml). A solution of 2S,3R-6-(2-trimethylsiloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-oxo-7-nonenyl)-3-trimethylsiloxyoxepane (452 mg) in tetrahydrofuran (5 ml) is added to this reagent and the resulting mixture is stirred for 10 minutes. An excess of trimethylsilyl chloride (150 mg) is added to this mixture and the mixture is allowed to warm to room temperature. The mixture is filtered and the filtrate is treated with pentane (30 ml). The resulting mixture is filtered again and the filtrate is concentrated in vacuo to afford 2S,3R-6-(2-trimethylsiloxyethylidene)-2-methyl-2-(4,8-dimethyl-5-trimethylsiloxy-5,7-nonadienyl)-3-trimethylsiloxyoxepane.

The following general procedure is a standard procedure employed to detect uterine contractions in female animals.

PROCEDURE I

Mature female New Zealand rabbits are anesthetized with sodium pentobarbital and ovariectomized. Following a recovery period of one week, the rabbits are treated with 5 μg./day s.c. of 17β-estradiol for 6 consecutive days, followed by treatment with 1.0 mg./day s.c. of progesterone for 7 consecutive days. The uterus and oviducts of the rabbits are perfused 72 hours after the last dose of progesterone according to the method of Heilman et al., (Fertil. Steril. 23:221-229) with slight modifications. The oviduct and uterus are perfused at a rate of 53 μl./min. The uterus is perfused with a tube extending 1.0 cm. into the lumen of the uterus from the oviducal end. The uterus is ligated at the utero-tubal junction. Another cannula is inserted 1.0 cm. into the uterus through a small incision in the vagina in order to collect perfusate. The material to be tested is administered i.v. through the jugular vein in a vehicle that contains polyethylene glycol 200, polyethylene glycol 400, ethanol and a phosphate buffer. The cannula is attached to a P23-Dc Stathan transducer which in turn is coupled to a Grass Model 5 polygraph and the uterine contractility measured.
